Forgot the name of the level, but it was the one where you stab the barrel. I was there for 1 hour unsure of what I had to do. Kept on thinking I had to survive so I thought it was hard. Of course when I finally did it it wasn't that hard, but damnit, only if I figured that you had to knock down the barrel.

I just did this and it was super frustrating. They really do not clearly indicate that this is what needs to be done.
